Description

The invention relates to a ventilation device with at least one outflow unit, which is displaceably mounted in a receptacle of a trim part of a motor vehicle. Such a ventilation device is arranged on a vehicle dashboard and mounted in the vehicle dashboard that the exhaust unit in an active state allows an air supply to a vehicle interior and is added in a passive state at least partially in the receptacle of the vehicle dashboard.

Various ventilation devices are known from the prior art, which cover a discharge unit in the passive state. Such a ventilation arrangement for motor vehicles is out DE 10 2011 100 059 A1 known. The ventilation arrangement comprises a console with a console surface in which a receptacle is formed. The console can be arranged for example on the vehicle dashboard of a vehicle. Further, the ventilation arrangement comprises a movable on the console air vent, which can be moved to an open and closed position, the air vent in the open position protrudes from the receptacle and is at least partially recessed in the closed position in the receptacle. The air vent is mounted to spend from the opening to the closed position and vice versa pivotable about a parallel to the air outlet surface extending pivot axis in the recording.

The ventilation arrangement of DE 10 2011 100 059 A1 requires a relatively large swivel surface on a vehicle dashboard. This means that on the vehicle dashboard a larger area is required for pivoting the air vent, as the actual effective area, ie outflow or Ausströmöffnung the Luftausströmers. At least one area of the vehicle dashboard must be provided for the air vent, with much of this area not being used to vent the air. In addition, the appearance of the dashboard changes significantly in the open and closed positions.

From the DE 41 36 822 A1 An air exhaust device for the interior of motor vehicles is disclosed. This Luftausströmvorrichtung is provided with a provided in the end portion of an air duct, for controlling the outflow of the air flow movably arranged ventilation nozzle and one of these downstream associated aperture, with webs separated, slit-like outflow openings. The air guide elements of the ventilation nozzle are aligned with the webs in a selected outflow direction. The air guide elements are arranged on a ventilation nozzle which can be moved about an axis of rotation, and the ventilation nozzle is drive-connected to a step mechanism of an actuating device in such a way that the air guide elements are aligned with adjacent webs of the diaphragm in each selected outflow direction.

DE 601 21 969 T2 discloses an air duct nozzle having an opening / closing assembly and a vent set that are movable together. The vent set is movable in a housing channel and the opening / closing assembly is movably mounted to the housing and movable between a closed position and an open position. An opening / closing flap of the opening / closing assembly has an outer surface and a pair of side members, each side member having an arcuate slot formed therein engaged by a respective guide pin which is movable in communication with the housing. Movement of the guide pins causes movement of the opening / closing assembly between the open and closed positions, which in turn causes movement of the vent set between the extended and retracted positions. However, such an arrangement entails the risk of jamming when, for example, contaminants enter the arcuate slot.

It is therefore an object to provide a ventilation device with an outflow unit, which in the active state (open position), when air is guided in a passenger compartment via the outflow unit, and in the passive state (closed position) when no air is guided into the passenger compartment via the outflow unit , Provides a substantially homogeneous surface on the dashboard or a clothing part of a motor vehicle and no space for the ventilation device is used, which extends into the passenger compartment via the trim panel or dashboard. In this case, the air should flow out through an opening of a trim part of a motor vehicle in the active state and the opening be concealed in the passive state.

The object is achieved by a ventilation device having the features specified in claim 1. Advantageous developments are specified in the dependent claims in detail.

Under a Maltese cross gear is generally understood a gear which has a star wheel, which is named after its characteristic, similar to the Maltese cross component. With a Maltese cross gear, continuous rotations can be converted into intermittent rotations or the number of rotations can be limited. Classic star wheels have four slots for this purpose. In addition, there are star wheels in Maltese Cross gearboxes, which have more than four slots. In addition, a Maltese cross gear on a drive wheel, which has at least one pin which engages with each rotation in a slot of the star wheel and this entrains until the pin exits the slot again. The drive wheel may have a circular sector-shaped locking disk, which engages after the exit of the pin from the slot of the star wheel in an area between two slots or a slot adjacent areas and holds the Maltese cross on the circumference, so that the star wheel is not further rotated.

The aeration device described herein, in contrast, has a Maltese cross gear in which the drive wheel has a first pin and a second pin lying on an opposite side and a first star wheel element and a second star wheel element have a first receiving slot and a second receiving slot. The first star wheel element and the second star wheel element need not be rotationally symmetrical. The arrangement and design of the components of the ventilation device allows opening of the closure unit and a method of Ausströmeinheit by rotation of the first drive wheel in a first direction of rotation. To return the outflow unit and to close an opening of the trim part by the closure unit, the first drive wheel must be rotated only in a second direction of rotation. The arrangement of the first pin and the second pin on the drive wheel specifies, at which distance to each other, the various movements, d. H. the pivoting of the closure unit and the method of the outflow, done. Thus, for example, already during the pivoting of the closure unit, a process of the outflow unit can take place from a retracted position into a moved-ahead position. For this purpose, the distance between the first pin and the second pin is less than in embodiments in which first the closure unit is fully opened and then the discharge unit is moved from a retracted position to a moved forward position. The process of the outflow unit and the opening and closing via the closure unit during the return movement of the outflow unit can therefore be carried out in such a way that the two movement sequences are superimposed or subsequently executed.

The formation of the aerator allows for moving the shutter unit and pivoting the shutter unit to an open position by rotating the first drive gear in a first direction and a closed position by rotating the first drive gear in a second direction, the second direction being directed opposite to the first direction , As a result, it is possible to dispense with a plurality of drive units or separate drives. The arrangement makes it possible for the outflow unit to provide the air supply of an air flow into the passenger compartment in the open position, wherein essentially only the outflow opening of the outflow unit is visible. In the closed position, an opening on the covering part is closed by the closure unit. The closure unit can be designed so that it fits seamlessly into the external appearance of the trim panel. The outlet opening of the discharge unit also closes substantially flush in an open position the surface of the trim part of the motor vehicle. In this case, the ventilation device makes it possible to provide an air flow via an outflow unit, wherein no further surfaces of the trim part are required for pivoting the closure unit and the method of the outflow unit.

In addition, two different movements of different components via a single drive can be realized, which provides for rotation in the open position and for bringing into the closed position only in one direction, a rotation of the drive wheel.

The ventilation device can also be designed such that

• A second drive wheel, a first star wheel element and an opposite second star wheel element of a second Maltese cross gear are arranged on the receptacle,
• The axis of rotation of the second drive wheel is at a distance from the axes of rotation of the first starwheel element and the second starwheel element,

• The second star wheel element has, on a side opposite the second receiving slot, at least one third pin, which is rotatably coupled to a second connecting element,
• - The second connecting element has a connecting portion which is rotatably coupled to the Ausströmeinheit, and
• - The connecting portion is displaceable in a second guide in the receptacle.

A ventilation device with two such Maltese cross gears, which are arranged on two opposite side walls of the receptacle, allows a synchronous pivoting of the closure unit and a synchronous method of Ausströmeinheit. In such embodiments, only one drive unit can be provided.

The first drive wheel may be coupled to the second drive wheel. This makes it possible to realize with a single drive unit, a synchronous pivoting of the closure unit and a synchronous method of Ausströmeinheit. With only one drive unit and the space required for the drive unit space is reduced because it can be dispensed with other components.

The first drive wheel and / or the second drive wheel may be coupled to the drive unit via a transmission. A gear arrangement provides a corresponding over- or reduction of a rotational movement, which is transmitted via the drive unit to the first drive wheel and / or to the second drive wheel.

The receptacle in the trim part may have a first opening for the outflow unit and at least one second opening, which is arranged adjacent to the first opening. In one of the second opening associated receiving portion of the receptacle, at least one air guide element can be mounted pivotably. By way of the at least one air-guiding element in the second opening, an air supply can also be provided in the case of a closed ventilation device. Preferably, via the at least one second opening an air supply in a certain direction. For example, aeration devices located in the area of a side window on a vehicle dashboard may continue to provide airflow to the side window in the closed position. The air supply to the side window can be provided both in the active state of the outflow unit and in the passive state of the outflow unit. In further embodiments, it is provided that the air flow is provided to the side window in a closed discharge unit via a pivoting of air guide elements. The pivoting of the air guide elements takes place in the context of a positive control. This means that when closing or in the closed state of the closure unit automatically the at least one air guide is pivoted so that an air flow is provided on the side window. If the closure unit is pivoted upwards again and the outflow unit is moved forward, so that an air flow is provided via the first opening via the outflow unit, a common pivoting with air guiding elements of the outflow unit can take place via the air guiding element in the second opening. This means that in the open state, the positive control can be abandoned and the at least one air guide in the second opening, for example, is pivoted synchronously with air guide elements of the exhaust unit.

The outflow unit can pivotably mounted on a housing of the discharge unit mounted first air guide elements and pivotable in the Housing mounted second air guide elements which are mounted orthogonal to the first air guide elements, wherein the at least one air guide element is coupled to the first air guide elements and / or the second air guide elements. The first and second air guide elements in the housing of the outflow unit may be lamellae, which are pivotable via an operating element. The control element can be arranged for example on a horizontally extending control blade, with a movement of the control element causes a corresponding pivoting of the horizontally extending blades up and down. The control element is further coupled with vertically arranged slats, so that a displacement of the operating unit along the horizontally extending control blade causes pivoting of the vertically extending slats. In further embodiments, for example, the vertically arranged lamellae extend downwards over the housing of the outflow unit, so that they also project into an air duct, which is assigned to the receiving section for the at least one air guiding element. The air flow output via the second opening can then be controlled in addition to the first air guide element via the vertically extending fins. When the air flow is closed, the vertically extending lamellae are preferably brought out via the outflow unit by pivoting a closure flap of the closure unit and returning the outflow unit to a forced position. In this forced position, the vertical slats are pivoted so that they direct, for example, the air flow through the second opening to an adjacently arranged side window. In one embodiment, the at least one air-guiding element, which is arranged in the receiving section with the second opening, is pivotably coupled to the horizontally extending plates. In an open state of the ventilation device, therefore, the at least one air guide element can be pivoted together with the horizontally extending slats. If the outflow unit is moved back and the closure unit is pivoted, the at least one air-guiding element is decoupled from the horizontally extending blades, so that the at least one air-guiding element automatically assumes a specific forced position. If the outflow unit moves forward again, then the at least one air guide element is coupled via a coupling arrangement again with the horizontally extending slats such that the at least one air guide element is pivotable together with the horizontally extending slats and occupies a certain position of the horizontally extending slats.

The receptacle may have a third guide arrangement, via which by means of a coupling device which is coupled to the at least one air guide element and the first air guide elements and / or the second air guide elements, the alignment of the first air guide elements and / or the second air guide elements in a retracted position of the discharge unit can be stored, wherein a control member is received in the retracted position of the discharge unit in the third guide arrangement. The coupling device may have a coupling rod, which is connected to the horizontally extending fins and connected via a further arrangement with the air guide. In an advanced position of the outflow unit, wherein an air flow is output via the outflow unit, a synchronous pivoting of the at least one air guiding element with the horizontally running lamellae takes place. If the outflow unit is moved back, then a pin or pin of the at least one air-guiding element, which is guided in a slot of a connecting piece pivotably and displaceably connected to the coupling rod, can be moved from a first position into a position. In the first position, wherein the outflow unit is in the advanced position, there is the synchronous pivoting with the horizontally extending slats. In the second position, wherein the outflow unit is in the retracted position, the at least one air guide element assumes a forced position. In order to store the orientation of the horizontally extending slats - first air guide elements - has, for example, the coupling rod for the horizontally extending slats designed as a pin control member which can be pushed into different guides of the third guide assembly. The guides are designed so that in a forward position of the discharge unit, the control member can be moved freely and in a retracted position of the discharge unit, the control member is received in one of the guides of the third guide assemblies. The separating sections arranged between the guides can be bevelled so that the control element is always transferred into a guide and blocking is prevented.

In further embodiments, the housing has a fourth guide arrangement and a first guide opening, the receptacle a first guide slot and a guide opening, and on the receptacle is rotatably mounted a guide element which has a second guide slot and a first control pin, wherein a first air guide element or a second air guide element having a second control pin which protrudes beyond the first guide opening out of the housing and is guided on the first guide slot and the second guide slot. The first control pin is guided in the second guide opening and extends in the direction of the housing, wherein the first control pin in the retracted state of the outflow unit is received in a guideway of the fourth guide arrangement. About the fourth guide assembly on the housing, for example, the position of the vertically extending slats are stored in the retracted position of the discharge unit, wherein in the retracted position a forced position is taken. The arrangement and design described above allows the storage of the position of the vertically extending slats, wherein the vertically extending slats in the retracted position then occupy a different orientation. The orientation assumed in the retracted position is predetermined by the design of the guide slots. Ie. when returning the Ausströmeinheit the vertically extending slats are pivoted in a certain direction. For example, the vertical slats are pivoted so that an air flow is deflected laterally, for example, to a side window. If the outflow unit moves forward again, then the vertical slats are pivoted so that they assume the previously set orientation again.

The axis of rotation of the first star wheel element and the axis of rotation of the second star wheel element can lie on a common axis. Furthermore, the first pin and the second pin of the first drive wheel and / or the second drive wheel may be arranged offset from each other about their axis of rotation at an angle between 90 degrees and 150 degrees. In such an embodiment, the method and opening or pivoting of the closure unit takes place staggered in time. However, even with smaller deviations, the individual motion sequences can take place at least partially overlapping. It is important that a method of Ausströmeinheit takes place only when the closure unit has been pivoted so that there is no blocking.

The drive unit may comprise an electric motor. The electric motor is operated via a control unit. The control unit may be arranged in the immediate vicinity of the opening on the trim part of the motor vehicle or at a remote location. The control unit may also be part of a controller for further arranged in a motor vehicle components such. B. an air conditioner.

Instead of an electric motor and mechanical rotary wheels can be provided which allow a manual adjustment or method of Ausströmeinheit and pivoting of the closure unit. In further embodiments, the first drive wheel and the second drive wheel are coupled together via a gear arrangement and a shaft. The first drive wheel and the second drive wheel are then coupled to the drive unit, wherein a transmission of the rotational movement takes place on the respective other drive wheel. A single drive unit reduces the cost of the ventilation unit and also reduces the weight of the ventilation device. In addition, a smaller space for the ventilation device is needed. Further, the control of, for example, electronic components, in particular with regard to a synchronous pivoting and method, easier to implement, if only a single drive unit is provided.

The receptacle for the ventilation device may itself be a housing for the components for the ventilation device. A further housing of the outflow unit is then displaceably mounted in the housing, wherein the components interact with one another in the above-described modes of operation.

Further advantages, features and design options will become apparent from the following description of the figures of non-limiting embodiments to be understood.
